You mean this piece?

3:
        movw    $0x0007, %ax                                    /* reset DS alias base */
        movl    ___djgpp_ds_alias, %ebx
        movl    ___djgpp_base_address, %edx
        movw    ___djgpp_base_address+2, %cx
        int     $0x31
 
Well, it seems like it shouldn't be too hard to move to sbrk16.asm.
But I think it is better to find out real causes for failures first.
